Embodiment 1

[0010] Example 1: The expanded graphite of 9980180 is expanded at a high temperature of 960°C by an extruding furnace, and short carbon fibers are added and mixed evenly and sent to a braiding machine for braiding and shaping. The length is 10m and the diameter is 18mm. The average resistivity at room temperature is 0.2Ω m The tensile strength is 35MPa.

Embodiment 2

[0011] Example 2: The expanded graphite of 9950250 is expanded at a high temperature of 960°C by an extruding furnace, and the continuous carbon fiber is added and mixed evenly and sent to the braiding machine for braiding and shaping. The length is 20m and the diameter is 20mm. The tensile strength is 38MPa.

Embodiment 3

[0012] Example 3: The expanded graphite of 9950250 and 9980200 is mixed according to the ratio of 1:1, and expanded at a high temperature of 960°C-1000°C in an extruder furnace, and then mixed with continuous carbon fiber and sent to the braiding machine for braiding and shaping, with a length of 30m and a diameter of 22mm. The measured average resistivity at room temperature is 0.25Ω·m, and the tensile strength is 40MPa.

Abstract

The invention relates to a carbon fiber anti-lightning, anti-static, and anti-breakdown grounding electrode. The present invention uses natural graphite mixed with carbon fiber to weave mechanically, and it is braided into various shapes and arbitrary lengths such as strips, strips, ropes, cylinders, etc. according to construction conditions, and stainless steel wires, copper wires, Reinforced with alloy wire, etc., its whole body is directly connected to the earth and buried, and one end is connected to the protected body. The invention has the advantages of good plasticity, excellent electrical conductivity, stable resistance, high tensile strength, acid and alkali resistance, high and low temperature resistance, long service life, convenient installation and environmental friendliness. The invention can be widely used in lightning protection and anti-static in many fields such as electric power, communication, transportation, finance, petrochemical, building systems and the like.

Description

technical field [0001] The invention relates to a carbon fiber anti-lightning, anti-static, and anti-breakdown grounding electrode. Background technique [0002] At present, there are many types of lightning protection grounding electrodes, including metal, non-metallic graphite, and mixed types. These products have disadvantages to varying degrees. Metals are not resistant to corrosion, especially in soils with high saline-alkali and chloride ion content, they are easily damaged by corrosion and fail, resulting in high costs, high energy consumption, toxic emissions, and environmental pollution. The service life is short; although the manufacturing cost of non-metallic graphite ground electrodes is lower than that of metal ones, it is easy to break and break, which is not convenient for construction. In places with dense population and clusters of buildings, and mountainous and rocky areas with high soil resistivity, due to the poor surface environment and limited construc...
